'Lake Kussharo' in the east of 'Hokkaido' is Japan's largest caldera lake.

Kussharo caldera slightly exceeds 'Aso' caldera in 'Kyushu' in size, boasting itself to be the largest caldera in the country. The specific size of it is 20 kilometers from north to south, and 26 kilometers from east to west. Ancient Lake Kussharo was a round shape as it was formed entire inner area of this huge caldera, but now it has become almost half size with a green pea shape. Japan's sixth largest lake though, aquatic life can be hardly found here since this lake water takes on rather strong acid pH. There stands one island in this lake, with the perimeter of 12 kilometers and the height of 355 meters above the surface of the lake. And this island has a crater on top. As many hot springs are gushing out in this vicinity, natural hot water gradually oozes out even from digging by hand on the lake shore.
